Subject: Is it possible to remove a print spool file using C?
Date: Tue, 23 May 2000 09:11:01 GMT
A current running application is creating spool
files when the network printer is down thusly, waiting for that network
printer to come back online to complete its job.
My question is, I have a daemon written in C, that re-issues a print job to
another printer on the network. I can't use "lpmove", don't ask me why
please. After I take the spooled file and print it to another printer, I
have to remove that file from the original spooler queue. If this is
possilble, how and what do I have to do?
Your help is much appreciated.
Thankyou,
Jeff

There was datasheet on their (PLX) website but I wasn't able to download
it because I had address containing word "spam" in it. Address was
really working [EMAIL PROTECTED] and I didn't
wanted to give any other address. This website claimed that I don't have
to use antispam addresses for their site ;(. So, are thay spammers?
Also they didn't answered to my mails.
About PLX9080 - I use one MUX of 8 RS-232-s here. Everything is ok even
without drivers except he multiplies all serial speeds to 8. So if you
use 300bps, real speed will be 2400bps. And there are equivalents for
many speeds but not for others like 115200.

Subject: How to get returncodes from init_module
Date: Tue, 23 May 2000 11:29:00 GMT
Hello mighty kernelhackers.........
I wrote a simple module with an 'init_module()' function that returns
different errorcodes for some cases (i.e. -ENOMEM for kmalloc()error
or -EIO for PCI errors). If I 'insmod' the module and it fails with
some of these errorcodes I get only the errorstring from insmod which
always fails with -1. Is there a simple way to see the returncode
from 'init_module()' (best would be directly on the terminal after
insmod !) ?? I tried 'strace insmod....' and also to start a
userprogram with a simple 'perror()' call directly after the
failed 'insmod...', but i was not successful.
Would be nice If someboby helps me.....

Did you install all the stuff by yourself? I currently do that with
the help of www.linuxfromscratch.org
Certainly interesting and one can easily configure each part of the
system during the installation phase, but quite a lot of work for Joe
User. But it's nice to see your system boot up without any of that
color stuff and sed, ed and vim being the only applications installed.

Gotta install XEmacs or Emacs soon...

the problem isn't with the install, it's when you go to remove or
upgrade. sometimes it's hard (or at least tedious) to figure out what
all things went where. then when you find a random file, you wonder
where it came from. rpm doesn't really solve the shared config
tweaks very well (like editing an init script to set something up
while leaving setup for other stuff). rpm is clunky and sometimes a
pain in the ass, but it's not completely useless to me.

Mr Steuber is an excellent example of my point. In my message can't you
tell I LIKE linux, I have Linux, I have used Linux for several years. It
is a great hobby to configure but once it is working what are you going to
use it for? Why don't any of the free ISPs support Linux? That would be
great. How can I spin down my SCSI drives when they are not in use? I've
been after that for years. Windows is no fun to install and configure, it
just basically works and you cannot really configure it. That means it
sucks if you want to spin down your SCSI drives because you can't. With
Linux you can do anything you want, well maybe, maybe somebody knows how,
maybe not. Maybe you post questions to boards and get real help, maybe
Dave answers. I still say "Great toy, bad technology".

I started before there were distributions. A colleague gave me his own
backup on 15 floppies. It was version 0.7?, I cannot remember exactly.
I just took it from there, compiling new software as it was made
available and advertised in comp.os.linux.announce or as it came in on
the local mirrors and announced on local usenet groups.
Cheers,

Subject: TL Workstation 4 sources reintall advice
Date: Tue, 23 May 2000 11:45:48 -0400
Hi. I have TurboLinux workstation 4.0 and have been
experimenting with development kernels and other sw.
After messing around with soft links I finally got things
to where a kernel source tree won't build anymore.
The links to include files are hosed, and although
I could probably follow the trail along and relink
to all the include files, it seems it should be less
hassle to just reinstall the sources.
Anyone have any suggestions for reinstalling system
and kernel sources with minimal disruption to my
system configuration etc.?
Just wondering if there's an easy way to reload stuff without
wiping the partition to get back to square one. I don't have
any important programming sources but odds and ends
I've downloaded and such.
TIA

I'm not arguing about your right to do whatever you want, I
am just saying that I don't understand what motivates you
to create a situation where I can download code, have it
on my machine and use it in any way I want, but only in
cases where I can do the linking myself. If another needed
component is controlled by someone else with an equal
right to choose their license, I won't be able to obtain
and use the combination together.

Lots of people make unenforcable claims but I don't want to take
that approach with the GPL. It is just that sanity I question.
Unless there really is a case for keeping it from competing
with commercial licensing of the same code (like ghostscript),
why give something away with strings attached that prohibit
a lot of uses?

Given a thousand packages, how long does it take you to be sure
you have the latest version of each installed using this
technique? How long does it take to figure out what is missing
when the linker can't resolve a symbol?

For whatever reason, a great many Linux and UNIX
users spend a lot more time working with Windows
than they might like, or like to admit.
As Tim O'Reilly says in "Windows by Day, Linux by Night ":
"...because we don't admit to our use of Windows, because
it's a guilty secret, we don't spend the kind of time learning
how to get the most out of the system. We do what we have
to, and then go home, to where we feel more comfortable.
That changed for me a year and a half ago."

Typically the configure script should tell you. That's what
it's there for. All a binary package buys you is the ability
to easily force install a whole bunch of stuff at once. In
the case of RPM, one is specifically abusing the tool in order
to get it to work in a more convenient fashion.

I would think that this is a FAQ, but based on my searches of
newsgroups, web sites, mailing lists, source code, and books, it appears
that no one has actually asked this question.
What is a dentry? I know it has to do with the file system, but I can't
find a definition of the word anywhere. I know it's not anything new
(2.2 has a structure called dentry), but the way people talk about it,
you'd think it was as well-known as the word "function" or "object".

Can Solaris also boot modularly on ix86 where the nice hardware is not

Anyway: to state from the beginning, doing I/O in drivers is wrong.
If you need to download firmware, do it from a user-level utility.
